Flowcharts for Biaxial Bending in R/C Tied Columns
Publication: Journal of Structural Engineering
Volume 114, Issue 6
Abstract
Flowcharts are presented for the analysis and design of biaxially and uniaxially loaded, reinforced‐concrete, tied columns in accordance with the “moment magnification method” of ACI 318‐83, section 10.11. Nonslender and slender columns in braced and unbraced frames are considered. The case of “appreciable” sway due to gravity loads in unbraced frames is also considered. The flowcharts can be used as step by step guides for manual computations or for coding subroutines in a computer program. The charts can easily be modified for any cross section shape and for other national or international codes. Where the wording of the American Concrete Institute code and commentary appears unclear, its intent is explored, discussed, and followed.
